o seat about the door and the accumulation of water within the outer casing of the range.

The invention is shown in the accompanying drawings in which Figure 1 is a front view and 151 Fig. 2 is a side view of a range embodying ithc invention.

Figs. 3, 4, and 5, are detail views showing the lower vent struct-ure m vertical section,

topplan, and elevation respectively.

ln these drawings 1 indicates the Outer cas ing of the range. The numeral 2 designates the oven, which is spaced apart from the wall f of the outer casing, the intervening space being indicated at 3. The Oven wall is formed double, the outer wall section or shell being designated 2a, and the inner wall section or shell being indicated at 2b. These wall layers or shells are spaced apart for heat insulating purposes and the space 3 between the oven body and the wall of the outer casing Valso contributes to heat insulation. The door shown generally at D is hinged at its lower end to the outer casing or frame 1. It has a protuberant portion (l which is adapted to fit a seat 2c at the open front of the oven so as to seal the Oven spaceand retain the heat therein which is produced by any suitable form of burner indicated generally at B within the oven, such as the electric heater ordi narily used in the Armstrong range.

It is customary to have a vent in the door communicating the interior Oven space with the atmosphere. This in the present form of range is indicated at 4;. It-consists of a tui bular member extending through the door and open at all times to the outside as well as to the oven space. This vent at times is not suitici ent to prevent condensation of moisture within the oven and the lObjection has been experienced that, at times, dripping water 1929.Y serial No. 356,757.

around the door will occur and there will take place an accumulation of water within the outer casing of the range. y i y 1- I have found that by proviorlingV a vent between the air' space surrounding the oven body and the interior oven space, the objections just mentionedare avoided., ThisA vent is indicated at V; A, It consists 'of a ltubular member having a fiange 5, topi-lt against the Outer side ofthe outer lwall `2a of the oven, said tubular member extending across the space 3a between the outer and inner wall GEORGE EDWIN ATKINsoN, oF PROCTORVILLE, OHIO, Ass'IG'NR, 'BY AssIGN- I1.

sections 2a, 2b, and through the latter so that Y air space 3 is placed in communication with the interior of the oveni. For securing'this vent tube in place it is shouldered at 6y to `fit against the inner wall or shellQb and its end is crimped at 7 to embrace'theedge of tl'ie said inner oven wall. K I

In the operation of the rangeV it'will be understood that when the oven is heated, `'say' by an electric heating element or elements located therein, there'will be no material Vdegree of condensationlot vaporupon the interior of thel Oven wall. p

The vent inthe door allowsthe pressure within the oven lto become equalized substantially with the atmospheric pressure' of the room, and prevents steam from being forced outfaround `edges ot door or out'` into spaceV around body of oven. i

When the electric heaters are lturned Off and the oven cools down, condensation of the moisture will take place under ordinary practice and in suflicient degree to causedripping of'water around the door and into the outer'V casing of the range. Withmy improvement this will be prevented within the range of temperature of ordinary cooking operations because the vent V in the bottom of the oven will allow the previously warmed air inthe i space 3, between the outer oven wall and the i `casing of the range to enter the oven and` Obviated.

The heat insulating space between the layers 2a and 2b forming the double oven wall, is closed as shown by the drawings. The space 3 between the oven and the outer casing which contributes to heat insulation is also an air space completely closed except Yfor the vent V as shown by the drawings.

I claim:

1. A range having an oven with an air space between said oven and the casing of the range., means for heating the oven, located wholly within the same a door closing the onen front end of the oven, an air vent in the door communicating the interior of the oven with the room atmosphere, and an air Vent communieating the air space between the oven and the said casing with the interior of the oven, Substantially as described.

Q. AA range according to claim l in which the last mentioned air Vent consists of a tubular member flanged on `one endet-o tit against one vWall ot the double wall of the oven7 said tube extending between the walls forming the double wall, having a shoulder fitting against the other wall of the double Wall and having a flange crimped upon the Opposite side of said other wall to embrace said wall between itself and the shoulder, substantially 'as described.

3. A range accordingV to claim 1 in which the oven is vdouble walled forming aV closed air space therebetween and the last mentioned air vent comprises a tube extending between the walls of said double wall and across the `dead air space between them, substantially as described.

4. A range according to claim l in which the rOven is double walled forming an air space therebetween and the last mentioned air Vent consists of a tube extending between the walls of'said double wall and across the air space between them, substantially as described. y i

In testimony whereof, I aiiixmy signature.

GEORGE EDWIN ATKINSON.
